Need Help!- MTI-1 board

[skippyfix]

When my machine tool changes when I use m25 or m6 the mti-1 board will not come back on with out me pulling one of the fuses out of the board ? It is a new board and the machine has a new spindle motor, does anybody have any ideas what I can try??? I have had this mill for three months and have not made one part with it but have spent a lot of mony trying to get it up and running, PLEASE HELP

The advantage of a seasoned service engineer is that they have seen a specific problem and have put in the time to know cause, effect, and solution. I have never seen your problem. But if you give me your email address, I can forward my KTK service class notes to you. It may help.

Hello PM sent Thanks

I noticed on my new MTI-1 card the two resistors numbers R11 and R12 are 330 ohms 5 watts on the old board they are 150 ohms 5 watts would this cause the problems?

Hello all, I have set my machine to the KTK service class notes and now the MTI-1 board will work when i do a tool change, but when I just let the spindle run for about a hour and try to do a tool change the MTI-1 board will not start with out me pulling the fuse on the MTI-1 board, then it will run again but I can not do a tool change, after about 6 hours of running the board goes off and every time I pull fuse and put back in light on MTI-1 board only stays on for about 15 seconds? I have checked the board with a infrared temp gun and nothing is very hot on the board I have also opened cabinet and put a big fan in front of it to see if that helped but did nothing for the problem, anybody have any suggestions?????????? Thanks
